[libvirt] [PATCH] Avoid searching for windres when not building for cygwin or mingw.

[Diego Elio Pettenò]

Just checking for a windres tool might hit even on Linux systems when
building for Linux (e.g.: when using Gentoo and having built binutils with
multitarget support), and will then fail to link properly at the end of the
build.

Check the host string before deciding whether to look for windres or not.
